+Because syntax tree node types and highlight styles have to be

+various languages).
+
+It _is_ possible to [define](#highlight.Tag^define) your own
+highlighting tags for system-internal use (where you control both

+be picked up by regular highlighters (though you can derive them

+This function is used to add a set of tags to a language syntax
+via [`NodeSet.extend`](#common.NodeSet.extend) or
+[`LRParser.configure`](#lr.LRParser.configure).
+
+The argument object maps node selectors to [highlighting
+tags](#highlight.Tag) or arrays of tags.
+
+Node selectors may hold one or more (space-separated) node paths.
+Such a path can be a [node name](#common.NodeType.name), or
+multiple node names (or `*` wildcards) separated by slash
+characters, as in `"Block/Declaration/VariableName"`. Such a path
+matches the final node but only if its direct parent nodes are the
+other nodes mentioned. A `*` in such a path matches any parent,
+but only a single level—wildcards that match multiple parents
+aren't supported, both for efficiency reasons and because Lezer
+trees make it rather hard to reason about what they would match.)
+
+A path can be ended with `/...` to indicate that the tag assigned
+to the node should also apply to all child nodes, even if they
+match their own style (by default, only the innermost style is
+used).
+
+When a path ends in `!`, as in `Attribute!`, no further matching
+happens for the node's child nodes, and the entire node gets the
+given style.
+
+In this notation, node names that contain `/`, `!`, `*`, or `...`
+must be quoted as JSON strings.
+
+For example:
+
+```javascript
+parser.withProps(
+  styleTags({
+    // Style Number and BigNumber nodes
+    "Number BigNumber": tags.number,
+    // Style Escape nodes whose parent is String
+    "String/Escape": tags.escape,
+    // Style anything inside Attributes nodes
+    "Attributes!": tags.meta,
+    // Add a style to all content inside Italic nodes
+    "Italic/...": tags.emphasis,
+    // Style InvalidString nodes as both `string` and `invalid`
+    "InvalidString": [tags.string, tags.invalid],
+    // Style the node named "/" as punctuation
